Two simultaneously-accessible "earth" potentials. "just not exposed to touch when the box is shut."
Inside an enclosure is perfectly OK for bare hazardous live conductors - are you really suggesting we need to go further for differing Earthed conductors?
- Andy.
Yes it is, from an "ordinary persons" perspective.
However, I believe you pointed out that the armour was required to be accessible for testing purposes. So, what's your CDM risk assessment for a safe environment for maintenance (including inspection and testing) and decommissioning? BS 7671 says IP2X/IPXX/D ... are you suggesting a lesser requirement is acceptable?
Since it's reasonably practicable to take this into account, why put those carrying out inspection and testing at unnecessary risk?
